try to run a cleanup and remove all obstructed files from your local copy. Or better said: copy them to a save place! Now remove all .svn dirs from your copy and run an update on your local project and copy back the »obstructed« dirs/files. Hit refresh and commit it. That should fix the “obstructed” files.
The reason might be, you’ve copied from another repos some files – including – some .svn dirs.

Saved my “evening” – thanks for sharing the SVN hint

Wonderful article, a bunch of high-quality material. I’m going to point out to my girlftriend and ask them the things they think.
